AUTOMATIC POCKET FAN.

Application filed March 5, 1921.

To all whom it may concern:

Be it known that we, HYMAN SIRor and HARRY SIRo'r, citizens of the United States, residingat New York, in the county of New York and State of New York, have invented certain new and useful Improvements in Automatic Pocket Fans, of which the following is a specification.

The main object of this invention is the provision of a pocket fan useful in summer as a handy relief from the hot weather, and useful generally as a toy for children.

The above and other objects will become apparent in the description below, in which like-named characters of reference refer to like-named parts in the drawings.

Referring briefly to the drawings, Fig. 1 is a front elevational view of our fan.

Fig. 2 is a side elevational View of the same.

Fig. 3 is a rear elevational view of the same with the rear casing removed to expose the interior. r

Fig. 4: is a side elevational view of the same with a portion of the casing exposed to again show the'interior.

Referring now in detail. to the drawings, the numeral 1 represents the casing of our device, preferably cylindrical in form, having an extending tubular portion 2. A rod 3 is slidably mounted in said tube 2 and extends into the casing 1, said rod being pro- 1S rigid with said tube and surrounds said rod, the latter being provided with a rigid pin 8 which limits the outward motion of said rod. A coiled spring 6 surrounding said rod urges the latter outward.

A link 9 is pivoted to the rod 3 at 7 at one end and to a crank 10 at 11 at the other end,

' the latter being rigid with a gear 12. A pinion 13 rigid with a gear 142, lies in mesh with the gear 12, while a pinion l5 rigid about a shaft 16, lies in mesh with the gear 14. The shaft 16 is at the center of the casing 1, and a fan 17 is rigid about said shaft, a cage 18 being secured to said casing about said fan.

The operation of the device is now believed apparent. Reciprocal motion is given the rest 4 by, preferably, the thumb, while the device is held in one hand. Thus, through the rod 3, link 9, and crank 10, the gear 12 is rotated. This rotation is transmitted through the gears and pinions shown, and finally to the fan 17 at a relatively high speed.

We claim:

A device of the class described comprising a casing, a shaft pivotally mounted in said casing, a fan rigid with said shaft, a pinion rigid with said shaft, a tubular extension on said casing, a rod slidably mounted in said extension and extending into said casing, a pin rigid with said rod within said extension, a collar rigid with said extension iLDC surrounding said rod, a spring surrounding said rod between said pin and said casing,

said pin being adapted to engage said collar and limit the outward movement of said rod, a link pivotally attached to said rod within saidcasing, a gear rotatably mounted within said casing, a crank rigid with said gear, and rotatable means connecting said gear with said pinion whereby the rotation of said gear is transmitted to said pinion at an increased speed.

In witness whereof we afiix our signatures.
